This may seem similar to https://parenting.stackexchange.com/questions/18787/at-what-age-does-a-childs-moral-compass-form, but what i am referring to here is character in general. Like for example, both me and my wife can get extremely angry compared to an average person. My wife has such a tremendous memory to an extent that it is harder for her to forget negative events and move on. I was a child who had a million questions. At what age do children form these? My son is only 10 months old. We are worried he may inherit undesirable ones. Can we even consciously try to change if he forms any?
